Oh whoops, there's an error in how the block is processing page links. It's offsetting by one. So the zone ends up becoming the page, and the page ends up becoming the type / action. Thus why the links don't work (and probably why it's also showing "home"... because it can't find the page to then get the proper title).

Wiki+ home is showing correctly, it must be special :)

It is... that's not a Comcode page like the other three things you mentioned (it's a module, or more-specifically the content type of Wiki+ Page), so it's controlled by a different hook. :P

Automated response: Wrong page-link in hook

Remove stray : in content hook

A hotfix (a TAR of files to upload) has been uploaded to this issue. Only apply this hotfix if you absolutely need it and cannot wait until the next release of Composr (releases are more reliable and strictly tested). As of Composr version 11, the recommended way to apply a hotfix is by following the same steps as an upgrade (https://baseurl/upgrader.php, use the hotfix on the step “Transfer across new/updated files”). The upgrader will automatically skip files belonging to addons you do not have installed or that are newer on disk than in the hotfix. Otherwise, you can manually extract and replace these files (do not replace if your on-disk file is newer than the one in the hotfix). Always take backups of your site or at least files you are replacing before applying a hotfix. Not sure how to extract TAR files to your Windows computer? Try 7-zip (http://www.7-zip.org/).
